NART-R preview

This model is a non-separable type of bearing system whose inner ring is fixed to the side plates.
Since the circumference of the outer ring is spherically ground, it helps lighten a biased load (symbol R).

Note 1: The rotational speed limit value in the table applies to models with grease lubrication. With models using oil lubrication, up to 130% of this value is permitted.For more detailed specifications, please download the Product Catalog with the link in the Downloads section of this product page.
